Fig. 6 is a perspective view showing the state of use of the fixing mechanism fixing interface card of another embodiment of the present invention. Fig. 7 is a schematic view showing the state of use of another perspective view of the fixing mechanism fixing interface card of another embodiment of the present invention. The fixing mechanism 100 of this embodiment includes a rack 110 and a positioning member 120. In the present embodiment, the difference between the configuration and the above embodiment is that the rack 110 of the present embodiment has a first end portion 111, a second end portion 112 and a bent portion 115 connected thereto. The first end portion 111 and the second end portion 112 are connected to each other by a bent portion 115, and the first end portion 111 and the second end portion 112 correspond to each other, so that the shape of the rack 110 is substantially U-shaped. The first end portion 111 and the second end portion 112 are respectively provided with a plurality of helical teeth 114 arranged in sequence, and the helical teeth 114 are inclined downwardly in the direction of the socket seat 410.

The positioning member 120 of the embodiment includes two sliders 121 and two Opening 124. The first end portion 111 and the second end portion 112 of the rack 110 respectively pass through the two openings 124 of the positioning member 120, so that the positioning member 120 can be sleeved on the rack 110 and can be along the rack 110. The one end portion 111 and the second end portion 112 are arranged to reciprocately slide. The two sliders 121 are selectively engaged with one of the helical teeth 114, and the two sliders 121 are respectively disposed at the left and right ends of the positioning member 120 and correspond to the positions of the two openings 124. The material of the rack 110 and the positioning member in the embodiment may be plastic, acrylic or metal, and is not limited thereto.

Please also refer to Figure 8. Further, the detailed structure and the manner of use of the fixing mechanism 100 are described.

It is disposed in the gap 412, so that the rack 110 can be fastened to the bottom surface of the socket 410 so that it is not easily detached. Therefore, when the positioning member 120 slides along the first end portion 111 of the rack 110 and the second end portion 112, the positioning member 120 can abut against the interface card 200 along a pressing direction P1, as shown in FIG.

At the same time, when the first end portion 111 and the second end portion 112 of the rack 110 are relatively far away from each other, the oblique angles 1211 of the two blocks 121 are respectively corresponding to the adjacent two oblique teeth 114. In order to fix the position of the positioning member 120 without causing sliding, the positioning effect is achieved. Based on the above structure, the fixing mechanism 100 of the present embodiment can clamp and hold the interface card 200 and the socket holder 410 by the positioning member 120 and the bending portion 115 respectively, thereby achieving the pressing effect, and inserting the interface card 200 into the insertion box. When the socket 410 is in the middle, no tilt or vibration is generated, so that the display card can maintain normal operation.

Conversely, if the interface card 200 is to be removed, an external force may be applied to the first end portion 111 and the second end portion 112 of the second opening 124. The first end portion 111 is relatively close to the second end portion 112, thereby the bevel 1211 on the second stop slider 121 is removed from the oblique tooth 114, so that the positioning member 120 is away from the interface card 200 and can slide. Adjust the position to remove or replace the interface card 200.

In addition, in the embodiment, the rack 110 can also be changed into a general strap, that is, the rack 110 itself has flexibility, and the positioning member 120 is fixed on one end of the rack 110, and the other end of the rack 110 After passing through the positioning member 120, the slider 121 is fixedly engaged with one of the helical teeth 114 to achieve the effect of pressing the interface card 200.

It can be clearly seen from the description of the embodiments of the present invention that the fixing mechanism of the present invention can solve the problem that the conventional display card is installed in the socket of the motherboard when it is mounted through the structural design of the rack-and-positioning member. The weight and the excessively long plate area cause oblique deformation, which is liable to cause problems such as looseness of the display card or poor contact.

Compared with the prior art, the fixing mechanism of the present invention not only utilizes the structural design of the rack and the positioning member, but also functions to suppress the display card, so that the display card is inserted into the slot seat without tilting or shaking. At the same time, the weight of the display card can be dispersed so that it does not deform, so that the display card can continue to operate normally for a long time, thereby greatly improving the service life and reliability of the display card and the socket. Moreover, the design that the helical teeth and the oblique angles are mutually engaged is adopted, so that the fixing mechanism can be quickly and conveniently adjusted and fixed in use.

Although the embodiments of the present invention are disclosed as described above, it is not intended to limit the present invention, and any person skilled in the art can make shapes, structures, and features as described in the scope of the present application without departing from the spirit and scope of the present invention. And the quantity can be changed in a small amount, and therefore the scope of patent protection of this creation is subject to the definition of the scope of the patent application attached to this specification.
